CRICKET: Steve Smith has refused to get carried away with Australia's series-tying win in Chittagong, slamming his side for collapsing 14 times in their past 15 Test matches.

The skipper revealed the astonishing statistic himself in his post-match press conference, fed up that nearly every time Australia has walked out to the middle in the past 12 months it has resulted in a batting capitulation of varying degrees of seriousness.

Even in an ultimately comprehensive seven-wicket triumph in the second Test, Australia failed to put Bangladesh to the sword when it had the chance in the first innings.

Following on from David Warner's ton and solid 50s from Smith and Peter Handscomb, Australia should have been ruthless enough on a good wicket to drive Bangladesh out of the game, but instead lost 5-66 and led by only 72 at the change of innings.

In the end Nathan Lyon's 13-wicket performance made the collapse irrelevant, but Australia's losing run since Sri Lanka last year confirms that more often than not, batting slides are costing his team dearly.

"We've had 15 collapses in our last 14 games our analyst told me yesterday and that's not good enough for an Australian cricket team," Smith said. "That's something we really need to work on and rectify that in the next series, the Ashes.

"Losing seven or eight for a 100 or a bit more, that's a pretty reasonable collapse and if you do that on regular occurrences, you're not going to win a lot of cricket games. It's something we need to work on."
